HENRY F. SEGERT, OF LIBERTYVILLE, ILLINOIS.

MILK-COOLER.

- '1'0 all whom it may concern.-

, which the liquid may to .the trade,

Be it known that I, HENRY F. SEGERT, a citizen of the United States, anda resident of Libertyville, county of Lake, and State of Illinois, haveinvented certain new and useful Improvements in Milk-Coolers, of whichthe following is a specification, and which are illustrated in theaccompanying drawings, forming apart thereof.

This invention relates to those devices for cooling and purifyingliquids in which there is provided a cooled inclined surface over becaused to flow in a thin stream.

The object of the invention is to provide apparatus for the treatment offresh milk reliminary to its being bottled for shipment this treatmentbeing intended to lower its temperature and to destroy its animal odorand the flavor of vegetables eaten by the cattle from which it has beenobtained.

The invention contemplates a cooling device having a plurality ofinclined coolingsurfaces and means for causing the liquid to be treatedto drop or flow in a thin stream from one of these surfaces to the nextadjacent in order that it may be purified by intimate contact with theair.

The invention is exemplified in the structure to be hereinafterdescribed, and illustrated in the accompanying drawings, in which Figure1 is an end elevation of a milkcooler constructed according to theinvention. Fig. 2 is a side elevation of the same. Fig. 3 is a planview, some of the parts being removed. Fig. 4 is a sectional viewon theline 4 4 of Fig. 2, and Fig. 5 is a detail crosssection on the line 5 5of Fig. 3.

As shown in the drawings, there is provided a receptacle 10 for acooling medium,

preferably formed of sheet metal and having end walls 11 and 12 and sidewalls 13 14. The side walls, as shown, are each curved to form aplurality of downwardly and forwardly inclined surfaces 15 15 anddownwardly and backwardly inclined surfaces 16 16.

Each of the downwardly and backwardly inclined surfaces 16 is connectedto the next higher downwardly and forwardly inclined surface 15 by meansof a rounded edge 17, and a rib 18 is formed near the rear of each ofthe downwardly and backwardly inclined surfaces, preferably by means ofa fold in the Specification of Letters Patent.

material from which the walls of the receptacle are formed. This rib orfold is referably transverse to the direction of inc me of the surfaceupon which it is formed and, as shown, extends along the surface for itsentire length. It provides means for interrupting the stream of liquidflowing upon the surface and causes it to drop through the air to thenext lower cooling-surface.

A drain 19 is provided for collecting the liquid from the forward edgeof each of the lowest cooling-surfaces 15. As most clearly shown in Fig.4, these drains are formed by suitably curving the side walls of thereceptacle, and each connects, by means of an opening 20 in the end wall1 1, with a trough 2 1, extending as indicated at 23 24 in Fig. 4 and at25, Fig. 5.

The top of the receptacle is preferably left open, as indicated at 26,to permit access to its interior, and to provide for the circulation ofcold water within the receptacle a funnel 27 is formed upon the end wall12 and communicates with its interior by means of an opening 28. Anoverflowopening 29, is formed in the end wall 12 just-below the level ofthe upper edges of the side walls 13 14, and, as shown, thiscommunicates with a discharge-tube 30, which crosses the funnel 27.vided near the base of the receptacle for drawing off its contents.

- Preferably there is associated with the device a receiving bowl orbasin 32, which, as shown, is removably attached thereto by means of apair of sockets 33, formed on the end walls of the basin and adapted toreceive the upper edges of the end walls of the receptacle, as mostclearly shown in Fig. 2. The floor of the basin may be provided with adouble row of perforations 34 35, one of which when the basin is inplace is just over the inner and upper edge of the highest inclinedsurface of each of the two side walls 13 14 of the receptacle 10. Inorder that the entire contents of the basin may be discharged equallythrough these openings onto the walls of the receptacle, the floor ofthe basin is curved upwardly between these two rows of openings, asindicated at 36, Fig. 4

In use the liquid to be treated will be caused to flow in a thin streamover the outer A drain-cock 31 is shown as being pro-.

surface of the two side walls-13 14 of the receptacle, preferably bybeing, delivered tothe receiving-basin 32, from which it will run ordrop through the o enings 34 35in its floor. The liquid in owing overthe side walls of the structure will follow their con tour, except wheninterrupted by the ribs 18', from the edges of which it will drip ontothe next lower inclined cooling-surface. The trough 21, extending acrossthe end of'the receptacle, 'rovide's'means for collecting the liquidwhic'h haspassedover both of its side walls, and the device willpreferably be so placedtha't the-discharge-spout 22 will deliver to asuitablestorage-tank. (Not shown.)

Oommonly'when the device is in use a circulation of cold water will bemaintained within the interior of the receptacle by directing a streamof-running water into the mouth of the funnel 27 and'permitting'it tooverflow from the interior of the receptacle through the discharge-tube30. As the cooling-water having-the lowest temperature is delivered tothe receptacle near its base it will c'ome in contactwith those walls ofthe receptacle over which that-partof the liquid to'be treatedisflowing, which has already been somewhat cooled, and the mostefiicient use is'thjerefore made of the cooling medium. To'facilitatethe c'eaningof the inclined sur faces 16; the endwalls of thestructure are cutaway or serrated between these surfaces, a's'indic'ate'd at 37, Fig; 1.

If desired, a heated fluid may be employed within therece ptacle 10 andthedevicethen used'a'sa sterilizer or pasteurizer.
